Description

Note –

This command is available only in domains that are configured
to support clusters, such as domains that are created with the cluster profile.

Use the export-http-lb-config command to
export a load balancer configuration or load balancer into a file
that the load balancer plug-in can use. The default file name is loadbalancer.xml, but you can specify a different name.
Once exported, you manually copy the exported file to the load balancer
plug-in location before configuration changes are applied.

To apply changes to the load balancer without manually copying
the configuration file, use apply-http-lb-changes,
or configure the load balancer to automatically apply changes with create-http-lb. If you use these commands, you do not need
to use export-http-lb-config.

Options

-t--terse

Indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-formatted data for consumption by a script. Default is false.

-e--echo

Setting to true will echo the command line statement on the standard output. Default is false.

-I--interactive

If set to true (default), only the required password options are prompted.

-H--host

The machine name where the domain administration server is running. The default value is localhost.

-p--port

The HTTP/S port for administration. This is the port to which you should point your browser in order to manage the domain. For example, http://localhost:4848.

The default port number is 4848.

-s--secure

If set to true, uses SSL/TLS to communicate with the domain administration server.

-u--user

The authorized domain administration server administrative username.

If you have authenticated to a domain using the asadmin login command, then you need not specify the --user option on subsequent operations to this particular domain.

--passwordfile

The --passwordfile option specifies the name, including the full path, of a file containing the password entries in a specific format. The entry for the password must have the AS_ADMIN_ prefix followed by the password
name in uppercase letters.

For example, to specify the domain administration server password, use an entry with the following format: AS_ADMIN_PASSWORD=password, where password is the actual administrator password. Other passwords that can be
specified include AS_ADMIN_MAPPEDPASSWORD, AS_ADMIN_USERPASSWORD, and AS_ADMIN_ALIASPASSWORD.

All remote commands must specify the admin password to authenticate to the domain administration server, either through --passwordfile or asadmin login, or interactively on the command prompt. The asadmin login command
can be used only to specify the admin password. For other passwords, that must be specified for remote commands, use the --passwordfile or enter them at the command prompt.

If you have authenticated to a domain using the asadmin login command, then you need not specify the admin password through the --passwordfile option on subsequent operations to this particular domain. However, this is applicable only
to AS_ADMIN_PASSWORD option. You will still need to provide the other passwords, for example, AS_ADMIN_USERPASSWORD, as and when required by individual commands, such as update-file-user.

For security reasons, passwords specified as an environment variable will not be read by asadmin.

The default value for AS_ADMIN_MASTERPASSWORD is changeit.

--help

Displays the help text for the command.

--config

Specifies which load balancer configuration to export.

Specify either a load balancer configuration or a load balancer.
Specifying both results in an error.

--lbname

Specifies the load balancer to export.

Specify either a load balancer configuration or a load balancer.
Specifying both results in an error.

--retrieve

If set to true, retrieves the loadbalancer.xml file
from the remote machine. The default is false.

Operands

file_name

Specifies the file name and location of the exported
configuration.

If you specify a directory (relative or absolute)
but not a file name, the file named loadbalancer.xml.load_balancer_config_name is created in the specified
directory. On Microsoft Windows systems the path must be in quotes.

If you specify a file name in a relative or absolute
path, the file is created with the name you specify in the directory
you specify.

If you specify a file name but do not specify a directory,
the file is created with that name in the current working directory.

If you do not specify this operand, the default value
is a file named loadbalancer.xml.load_balancer_config_name created in the app_sever_install/domains/domain_name/generated directory.

Examples

Example 1 Using the export-http-lb-config command
on the UNIX platform

The following example exports the load balancing configuration mycluster-http-lb-config to a file named loadbalancer.xml in the /Sun/AppServer directory .
